TY - RPRT A1 - Bruns, Erich A1 - Bimber, Oliver T1 - Adaptive Training of Video Sets for Image Recognition on Mobile Phones N2 - We present an enhancement towards adaptive video training for PhoneGuide, a digital museum guidance system for ordinary camera–equipped mobile phones. It enables museum visitors to identify exhibits by capturing photos of them. In this article, a combined solution of object recognition and pervasive tracking is extended to a client–server–system for improving data acquisition and for supporting scale–invariant object recognition.

Second, they are not very intuitive. Reference numbers have to be manually keyed in by the visitor before information about the exhibit is provided. These numbers are either displayed on visible tags that are located near the exhibited objects, or are printed in brochures that have to be carried. Third, offering mobile guidance equipment to visitors leads to acquisition and maintenance costs that have to be covered by the museum. With our project PhoneGuide we aim at solving these problems by enabling the application of conventional camera-equipped mobile phones for museum guidance purposes. The advantages are obvious: First, today’s off-the-shelf mobile phones offer a rich pallet of multimedia functionalities ---ranging from audio (over speaker or head-set) and video (graphics, images, movies) to simple tactile feedback (vibration). Second, integrated cameras, improvements in processor performance and more memory space enable supporting advanced computer vision algorithms. Instead of keying in reference numbers, objects can be recognized automatically by taking non-persistent photographs of them. This is more intuitive and saves museum curators from distributing and maintaining a large number of physical (visible or invisible) tags. Together with a few sensor-equipped reference tags only, computer vision based object recognition allows for the classification of single objects; whereas overlapping signal ranges of object-distinct active tags (such as RFID) would prevent the identification of individuals that are grouped closely together. Third, since we assume that museum visitors will be able to use their own devices, the acquisition and maintenance cost for museum-owned devices decreases.

It provides additional location- and object-aware multimedia content to museum visitors, and is scalable to cover a large number of museum objects.

Our main technical achievement is a simple and light-weight object recognition approach that is realized with single-layer perceptron neuronal networks. In contrast to related systems which perform computational intensive image processing tasks on remote servers, our intention is to carry out all computations directly on the phone. This ensures little or even no network traffic and consequently decreases cost for online times. Our laboratory experiments and field surveys have shown that photographed museum exhibits can be recognized with a probability of over 90%. We have evaluated different feature sets to optimize the recognition rate and performance. Our experiments revealed that normalized color features are most effective for our method. Choosing such a feature set allows recognizing an object below one second on up-to-date phones. The amount of data that is required for differentiating 50 objects from multiple perspectives is less than 6KBytes.

Museum of Solidarity N2 - The artistic research work is concerned with webs of transnational artistic solidarity, especially those ingrained in the Nonaligned Movement (NAM), which embraced differences and united them in a common anti-imperialist and anti-colonial fight. Taking the museum as an artefact of historically situated solidarity, the project examines the instruments of transnational art solidarity for conceiving, developing and implementing decolonial cultural practices today. The main research question regards thinking about whether and how the emancipatory potential of the transnational art solidarity can be extracted, recuperated and translated when dealing with present issues of cultural decolonisation. Three museums founded on the bases of international solidarity and donations of artworks form the case study. Consequently, the research findings are systematised in three discourses: The Autonomous Museum; The Decolonial Museum; and The Museum in Exile. N2 - Die künstlerische Forschungsarbeit befasst sich mit den Netzwerken der transnationalen künstlerischen Solidarität, insbesondere denen, die zwischen den Ländern des Globalen Südens zwischen den 1960er und den 1980er entstanden sind. Ausgehend von dem Museum als einem Artefakt historisch verankerter Solidarität untersucht das Projekt die Instrumente der transnationalen Kunstsolidarität für die Konzeption, Entwicklung und Umsetzung dekolonialer kultureller Praktiken heute. Die Hauptforschungsfrage besteht darin, ob und wie das emanzipatorische Potenzial der transnationalen Kunstsolidarität für die Auseinandersetzung mit aktuellen Fragen der kulturellen Dekolonisierung genutzt, zurückgewonnen und übersetzt werden kann. Drei Museen, die auf der Grundlage von Schenkungen von Kunstwerken gegründet wurden, bilden die Fallstudie. Folglich werden die Forschungsergebnisse in drei Diskursen systematisiert: Das autonome Museum, das dekoloniale Museum und das Museum im Exil.
